The first part is just background information I only need help with the marked section, thank you!

A researcher collects data between the age in years, (x), of
a movie theater's popcorn popper and the cost of its
monthly maintenance, (y).
Find the regression equation. Round b to three decimal
places.
ŷ =
+
Fill in the table to find the residuals. Round table entries
to three decimal places.
y – ŷ

What is the correlation coefficient? Round to three decimal
places.
Graph the data and find the outlier. Give the ordered pair
here:
If your ordered pair is actually the outlier, then the
correlation coefficient would increase. Delete the ordered
pair you chose and find the correlation coefficient again.
Type the new correlation coefficient rounded to three
decimal places here:

Put the outlier back into your data and then find the test
statistic, p-value, df, and critical value(s) for a test to find
if there is a positive correlation with a = 0.01. Round to 3
decimal places

p-value =
df =

Your final conclusion is that...
There is not enough evidence to show that there is
a positive correlation between the age of a popcorn
popper and its monthly maintenance costs.
